This, invention relates to a washing installation in which the water is discharged in the form of a free jet,.above the edge of the Washing basin.

Washing installations of this kind are usually so constructed that a plurality of jets are delivered so as to permit the use of the installation by several persons at the same time. The known devices of this kind are liable to disturbances in operation since, the narrow ports of the, jet forming member tend to be choked by depositions of the water or foreign substances in the water. These defects occur particularly with circular jet forming members distributing the water into one or more washing basins of round or oval shape.

It is the object of this invention to remove these defects and to provide a washing installation which does not tend to obstruction and can be easily disassembled and cleaned.

Another object of the invention is to facilitate the production of the device and to avoid the use of expensive materials for the device.

, With these and further objects in view, my novel. device comprises concavely curved guiding surfaces over which the water extends as it is discharged from the feeding duct. These guiding surfaces are preferably parabolically shaped, more particularly like a mushroom, and may be providedwith grooves. Thus, as will be understood, the water flows down from the guiding face in the form of jets, bands or veils, depending on the available pressure and the form of the guiding face.

The water outlets in the feeding duct are preferably provided in the abutting face or faces of adjacent composite parts of the jet-forming member so as to be readily accessible, by disassembling these parts, for cleaning the ports or outlets.

The invention will be better understood by ref erence to the following detailed description in connection with the accompanying drawing, showing by way of example and schematically some embodiments of the invention, viz

Fig. 1 is a longitudinal section of a washing installation having the invention applied thereto.

Fig. 2 is a longitudinal section, on an enlarged scale, of the crown of a modified form of the in- Fig. 6 is abottom view of a guiding surface having grooves extending over a part of the guiding surface only, namely, near the outer edge thereof.

Referring now to the drawing, and first to Figs. 1, 2 and 4, it will be seen that the water, heated to the desired temperature in any suitable manner, is fed, through the feeding tube I which delivers the water'to the guiding plate 3 of parabolic cross section so that it is distributed on the underside of the guiding plate and streams along the same and passes on, in the form of a parabolic jet, into the basin 4.

The member 3 which forms the guiding face is interchangeably mounted on the columnB, so as to render it possible to replace the member 3 by one having another shape, more particularly a guiding face of another form and to render it possible toproduce the apparatus in a greater number of smaller component parts. 7

It will be seen that the guiding member 3 is provided with grooves 1, l spaced apart for uniform distribution of the water delivered by a conically extending upper portion 8 of the feeding tube l. The walls of the conicalmouthpiece 8 and of the lower conical portion H) of the member 3 defining together a hollow mouth piece chamber are smooth and not grooved and the angle'of the cone of the mouth piece 8 is more acute than that of the cone of the portion [0, so as to form the said mouth piece chamber. The water enters into this chamber through ports I l in the feeding tube 9.

The grooves 1, l in the portion ID are tightly covered by the upper rim of the mouth piece 8 so that tubular outlets are formed which, however, can be easily cleaned after removal of the guiding member 3.

As shown in Fig. 6, the guiding grooves may be in a part of the guiding surface only, for instance, in the marginal portion. These grooves may be subdivided in groups, by ledges I2 and I3 extending over the whole guiding surface or over a part thereof, so that the water is separately fed to the single groups of grooves.

Bundles of jets may be produced by providing adjacent grooves l of different depth.

I prefer to increase the cross section of the grooves in a radial outward direction, so as to make up for the reduction of the velocity of the Water. This increase of the cross section may be effected by increasing the grooves in width, as at 1 in Figs. 2 and 4, or by increasing the depth of the grooves, as indicated at l' in Figs. 3 and 5.

While I have herein shown and described certain preferred embodiments of my invention, I wish it to be understood that I do not confine myself to all the precise details herein set forth by way of illustration, as modification and variation may be made without departing from the spirit of the invention or exceeding the scope of the appended claims.

I claim:
